|Title||Bursting the bubble: evolved AGN feedback in a galaxy group|
|Author||Dr Aurora Simionescu|
|Description||We propose a 42 ks observation of the galaxy group Nest 200047. LOFAR images with unprecedented sensitivity at low radio frequencies revealed a surprisingly complex filamentary structure related to the AGN feedback in this system, extending more than 200 kpc in radius. We interpret this unique morphology as being due to an old AGN bubble that is in the process of breaking up as it is buoyantly rising out of the group and interacting with the surrounding medium. To our knowledge, this is the most advanced stage of bubble evolution observed to date. The proposed exposure will allow us to quantify the morphology of the X-ray cavities associated with the large-scale radio lobes and perform a detailed analysis of the substructure and thermodynamical properties of this spectacular system.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
